li'nes at the decorating station for ware before the ware enters the dryer.

Fig. 19 is a plan view across the production lines at the decorating station for ware, after the ware leaves the dryer.

The decorating apparatus at F, Flg. 10A, and

station for Y P, Fig.` l0, are arranged across the production lines as shown in Fig. '18.

The decorating attachments are mounted on a standard form of carriage assembly substantially similar to that illustrated in Figs. 1 and 4, for the purpose of giving them the desired movements relatively to the ware on which they are to perform.

The reference numeral 85 designates vertical guide and stop posts which are adjustably secured in and depend from one ofthe top plates 38e of the machine (see Fig. 10A), a frame 85a shownas of rectangular shape being mounted to have a vertical sliding fit on said posts, nuts Mb being threaded on the lower extremities of said posts to adiustably limit the lowermost point oi travel of said trame. The frame 85a is formed with a bracket o, which is bored to receive a pivot bolt 85d, which is adjustably secured by nut 35d', a lever 85e being pivoted at one extremity in said bolt and at its opposite extremity adjust- .ably and plvotally supported from a post I5),

which also depends from and is secured in the top plate 30o. This lever 85e is provided with a cam roller 85e adapted for contact with various types of frame-actuating cams shaped in accordance with the worls involved and which are mounted on one of the cross shafts a, or if the variable speed assembly is used,on the sleeve n. these cams being shown in connection with the various attachments hereinafter described.

The lower portion of the frame a is formed with a dove-tail slot or groove in which a bar Mg is mounted to have a horizontal sliding lit, the bar at the left as viewed in Fig. 1 being formed with a vertical guide bracket 85h having a central slot or track 35h'. A lever 851 provided with a cam roller Bti' is pivotally and adiustably supported at its upper extremity from a post 8M, and at its lower extremity said lever is provided with a pin BMZ adapted to have a working ilt in said track 35h. As in the case of lever 85e, the cams for the lever 35i are given the required contour in accordance with the work involved and are mounted on one of the cross shafts alla or sleeve 68, each attachment generally requir- -ing a particular contoured cam which is illustrated in connection with the attachment.

The bar 85g is slotted at 85k, a pin 85k' being secured in the frame 85a, a compression spring 85M! being mounted to abut at opposite ends.

, respectively, against said pin and the bar 85g.

The bar 85g is also provided with a screw bracket 851 in which a contact screw 85m is mounted, which serves to adjustably limit the movement of bar ig in one direction independently of its cam travel or reverse movement. The screw bracket S35! adapted to be attached at either end oi 35g and the spring 85k? at either end oi? s 85k, to conform to the positive direction of movement of the cam lever 85i.

it will be seen that when levers 85e and @5i are oscillatecl, the frame 85a reciprocates vertically and the bar 85g laterally, the bar deriving its vertical movement from said frame. The frame is provided with screws 8511, and 850 adapted to be adjusted in contact with the posts S5 and frame 85a in the event the actuating cams are to be disconnected and the frame and bar set in rigid adjusted position.

An attachment and tool-mounting turret disk is supported from the slide bar 85g by means of a hanger bracket 86a, saidl bracket being formed with projecting hub portions 88a' and 88a! (see Fig. 6) and is secured to the bar 85g by screws 8MS, (see Fig. 4), the disk 86 being rotatably mounted on the hub 86a' and prevented from lateral displacement by a ring 88a4. A shaft 86h extends through and has bearing in the projecting hubs of bracket 86a, this shaft functioning in a manner which will later become ap-v parent. The disk may be rotated intermittently in one direction or oscillated, the detents 8lg and Sii being housed, respectively, in a gear 86o and the bracket 88a and adapted to register in det-ent or latch notches 8in and spotting notches 8H formed in one side of said disk 88, there being four of each of said notches in the present instance, The gear 86e is mounted to rotate free on the bracket hub 88a and the teeth 86e of said gear are in continual mesh with the teeth 86d of a rack 86d, the latter being slidably dovetailed into a groove formed in the bracket 86a (see Fig. 6), and terminating in a T-head 86d2, (see Fig. 1) which is formed with a track 86d3. The rack 86d is actuated by a bellcrank lever 88e, which is fulcrumed at 86e' on a bracket extension 8662 formed on the frame 88a, the one extremity of said lever 86e being provided with a pin 86e3 which has a sliding fit in the groove or track 86d3, while the opposite extremity of said lever has pivoted thereto a connecting rod 86! which extends through a guide bracket 88f8 and terminates in a T-head 86]" formed with a groove or track 8612, said T-head cooperating with a lever 86g pivotally supported at its upper extremity from a post 86h, which is secured in one of the top frame plates 88e, and at its lower extremity said lever is provided with a pin 86o' having a sliding fitrin the groove or track 8812 of T-head 86j. Lever 86g is provided with a cam roller '86g2 adapted to contact with a suitably shaped cam to be mounted on shaft 80a, these cams also being generally shown with the respective attachments hereinafter described.' A retracting spring 88114 is secured at opposite extremities, respectively, to the T-head 88d2 and the bar 85g.

A screw 861' is shown as threaded in the bracket 86a, (see Fig. 6), this screw being adjusted against the turret disk 86 when it is desired to maintain said disk stationary with said bracket. A screw 867' is also shown threaded in the hub 86112 of bracket 86a, and this screw may be adjusted against the shaft 86h when it is desired to maintain the latter stationary with said bracket.

The disk 86 is provided with a plurality of holes 86h: for attaching various fabricating tools and attachments.

asesina The shaft 85h be driven by either a positive or friction drive, both forms of drive being shown in Figs. 4 and 5 for the purpose of illustration.

A bevel gear 81, formed with a hub 81', is shown as adjustably secured on the shaft 8627, this gear meshing with a similar gear 81a secured on a stub shaft 81a' which has bearing inthe rejecting extremity of a bracket arm 88a! formed as part of the bracket 86a. A bracket 81b is adjustably supported by a post 81h from one of the top frame plates 38e and extends down and at' its lower extremity is formed with a foot 81b2, a stub shaft 81e having bearing in said foot, this shaft forming part of a fiexible coupling comprising a sleeve 81e and longitudinally grooved shaft 81c2 in spline sliding engagement with said sleeve, the lower extremity of shaft 8162 being coupled for universal movement with the stub shaft 81a on which gear 81a is secured. The stub shaft 81e of the exible coupling has adjustably secured thereon a pinion gear 81d, which may be replaced bya friction gear 81d (see Fig. 5), when a non-positive, intermittent or continuous high-speed drive is desired. If pinion 81d is'used, the drive s effected by means of a segmental gear 81e formed on a lever 81e', which is adiustably pivotally mounted on the bracket 81h and provided with a cam `roller 81e2 adapted to contact with a cam to be mounted on shaft a or sleeve 68 and which may be given various contours in accordance with the rotation desired for shaft 86D. The lever v81e' may be retracted by a spring 81f.

If the friction or non-positive drive is desired, the friction gear 81d' may be substituted for pinion 81d and a co-operating friction gear 81g splined or mounted for longitudinal sliding movement onshaft 80a or sleeve 68, the latter gear being formed with a hub having an annular groove 81g' formed therein. A grooved cam 81h, adjustably mounted on shaft 80a, transmits longitudinal sliding movement to friction gear 81g by means of a pin 811, slide rod 8112 and pin 81i the pins 81i and 8H being adjustably secured on slide rod 811'2 which in turn is mounted to slide longitudinally in adjustable supporting brackets 817 which extend upwardly and are secured in one of the frame plates 38e.

If the rotation of shaft 88h is to be alternately reversed, the drum cam 81h may be used. this cam movement causing the friction gear 81a to move across the face of gear 81d', and when the gear 81g passes over the vertical axis of gear 81d', the rotation of said gear will be halted and then reversed, thus reversing the drive on said shaft 86h.

The Jack shaft 88j of the change-"speed assembly is shown as mounted and having bearing in hanger brackets 811 which are also adjustably supported by posts 8112 from one of the frame plates 88c.

The decorating attachments, Figs. 2 and 16, are shown mounted on a turret 88 (see Figs. 'I and 8), which is secured to the disk 88 by screws 88a. This turret may be rotated in accordance with the particular attachments in use. If there are four attachments on the turret and all are being used in succession, the lever 86g may be actuated by a cam substantially similar to cam 88g3 (see Fig. 14).

Super and sub-atmosphere, electricity and other fluid mediums may be communicated to the various fabricating attachments that may ases-11o be applied to the turret disk 88 (see Figs. and 8).l

For super and sub-atmosphere, liquids and analogous fluids, the bracket 86 is bored to pro.- vide passages or ducts 13e and 'ISL which lead through the hub 86a and register with passages 13e' and 13j formed in the turret E3, these later passages terminating in annular grooves or chambers 1302 and 1312. The fragment of the turret 8B shown in Fig. 8 is provided with a rotating spindle or post which is formed with passages 13e3 and 13f3 which register at one extremity with said chambers and at their opposite extremities terminate at the point of application. Hose nipples 1394 and 1314 are secured in the bracket 86a (see Fig. 6), for connection of the air or fluid lines leading from pump line ie2, Fig. 9.

To supply the various attachments that may be applied to the turret 88 or disk 86 with electric current, the bracket arm 86a5 may be formed with a projection on which are secured brushes 81k and 811, Fig. 8, which are adapted to contact with suitably insulated commutator rings 81kand 811' secured in the adjacent side of the disk 8i, said rings being connected with another set oi' commutator rings 81k! and 8112 secured on the periphery of said disk and which in turn transmit the current to the attachment through contacts or rings k3 and 8113 securedin the orating freshly formed ware and station P for ware emerging-v from the dryer.

As the open bottom mold carrying traysl 39 bearing the ware progress along the lower main V operative relation with the decorating apparatus at stations F and P. lThe complete assembly is mounted on a skeleton frame 63 which is adjustably secured on'cross supports 03a, by screw bolts tlb, extending through enlarged openings, and centering dowels "c, .the latter being removed in the event it is desired to shift the unit from its initially aligned position. 'I'he cross supports a are suitably adjustably secured to the base of the main frame 3l of the machine. Thecasting or frame Il is provided with a bearing housing d for a spindle 64 (see Fig. 17), the lower extremity of which has secured thereon a collar c by means of a. pin Nb, said collar supporting a thrust bearing assembly comprising a tapered collar Hc, bearing rollers Mc', a saddle d and spring Ble, a cover 64I being adjustably threaded into the housing against which said springv abuts, so that the spindle moves upwardly against the tension of said spring and lowers by gravity assisted by said spring.

'I'he spindle il is in spline sliding engagement with a chuck spindle 82e on which the chuck B2 is secured by a screw BZcand dowel pin 62c'2, reciprocation being imparted to the chuck 62 and spindle 32o by means of a cam Bld, which is adjustably mounted on a cross shaft 62e having bearing in the side frame plates 38a of the 'main frame of the apparatus, saidcam actuating a lever tf, which is adjustably pivoted at one extremity, the pivoting assembly being supported from the frame t3, and at its opposite extremity pivotally secured to a pitman 62g, the pitmanA connecting with spindle c2c by means of a cross ieri: 5327i, which is adjustably secured to said pinnen. by nuts @in at its one extremity and forked into an annular groove in the spindle 82e at its opposite extremity. The pitman 52a pro- `iects through and is guided by extensions 6M of the frame 63, the upper end of said pitman having adjustably threaded therein a contact screw 62k, the functionl of which will later be-l .plates or beams 38a.

The friction gears 64g and Glh are brought into intermittent contact by a lever and brake assembly comprising a brake shoe 647' formed with studs for mounting the shoe lfor vertical movement on the frame 83, a b ellcrank lever 64k plv-.-

oted or fulcrumed in said trarne, a connecting rod Nl adapted to be-adJustably pivoted at one extremity in any one of a plurality of holes formed in said bellcrank lever and at its opposite extremity adjustably secured by nuts 84m on a pitman Mn, and cam contacting arms 6Go and 54p which are also adjustably secured on the pit- 'I'hese arms 64o v man 661i by nuts Nq and 641'. and 64p are alternately raised and lowered by separate cams, not shown, which are adjustably mounted on the shaft 62e and have a contour substantially similar to the valve cams shown in Fig. 9.' The frame 63 is formed with guide brackets tfor the pitman Mn. v

To vary the speed of rotationyof the chuck during reciprocation thereof the splined friction gear 84h is provided with a grooved hub Mh', also splined on shaft Gli, and a grooved cam h2 is adiustably secured on shaft 62e. motion being transmitted from the cam to said gear by a lever sms, which is adjustably pivotauysupported at its upper extremity on a bracket extension e of the frame 63, said lever extending downwardly and adjacent cam h2 being provided with a pin 64M working in the groove of said cam, and at its lower extremity said lever connects with the grooved hub Nh' by a link h5 and pin M working in the groove of said hub. f

In operation, the chuck reciprocating cam 32d and brake cams being adjusted to work in synchronism, when the chuck spindle and chuck elevate, the brake 64j is released permitting spindle 64 to lower and thus lowering gear Ma' into convtact with the continuously rotating gear 84h and To gradually accelerate and decelerate or vary the speed of rotation 'of the chuck during recip-` rocation thereof,'the drum cam Mh! and lever h3 may be used to move the gear h relatively` to gear Ng. Ordinarily, however, the brake. if

properly adjusted, will operate to eiiect gradual contact and release oi' the gears a and h and provide for smooth operation of the chuck I2.

The Shaft w, on which the wnunuounyurivm gears 64h are splined, and the cam shafts 62e are arranged so that they may be driven from the main drive shaft M, or, as shown in Figs. and 12, the shafts 641 may be driven from an independently .driven shaft 66 and the shafts 62e from shaft M, (note Figs. 10 and 10A and the reduced view Fig. 12), the drive being transmitted by helical gears 61 and 61a, the gears 61 being adjustably secured on-the shafts 66 and 4I and the gears 61a on the cross shafts 62e and. "i, The speed of rotation of shafts 62e and i may be independently varied along the fabricating line by simply changing the ratio of gears 61 and 61a. These latter gears are used at various points in the entire apparatus, as will be noted in Fig. 1.

The shaft 66 is supported in bearing brackets 66a, which project at intervals from the main frame of the machine, said shaft being driven by a motor 661) (see Figs. 10 and 19).

Super andsub-atmospheric pressure and other mediums may be applied to the molds through the chuck for various fabricating operations, the passages 62a and 62h extending down into the chuck spindle 62e as shown and opening out into annular registering air grooves 62a and 62h formed in a hood 1i! having a working t around said spindle and adjustably supported on the frame 63l by a thread rod 16a, hose nipples 62112 and 62122 being threaded into the hood 1l! and communicating with said grooves. A further communicating passage opening out in the bottom of the chuck is provided by a bore 'Il in the screw 62e', the interior of the spindle 62C being hollow, thus forming a chamber 11a, and the hood 10 having a further groove 1lb in communication with said chamber, a hose nipple 'llc being threaded into the hood 10 and communicating with said groove. Where the passages 62a, 62h and '1I open out into the chuck 62, resilient sealing and cushioning pads 621 are adjustably threaded into said chuck.

Thus at stations P or F are located these units which are capable of lifting molds and ware on the conveyor and providing the desired ware manipulation during decoration. In Figs. lo and 10A, the decorating assembly is shown installed in the fabricating line adjacent the dryer. at which point the Ware will have been shaped by the profile and be still in a soft or plastic state. At this point, it may be desirable to apply a coating of slip such as engobe, clay in a more or less plastic state and of a different color relatively to the ware, powdered, granular or fluid coloring or decorating material, and analogous decorative as Well as utility mediums. However, the apparatus may be installed at any point along the fabricating line, for instance, at the stations P or F as previously mentioned. e

The decorating attachments, Figs. 2 and 16, may be mounted on the turret 88 through the medium of the trunnion gear 89a (see Figs. 7

and 8). In Fig. 2 an attachment particularly adapted for decorating and shaping the interior of deep ware is shown, and comprises a decorating wheel 961 which is illustrated as beingsupported from a crosshead 961' which is secured in angular spotted position to the gear trunnion 89o by the pin or screw 89e, said crosshead being slotted for adjustable securement of bracket 967', decorating unit designated by 961, being pivotally secured to said bracket.

The member 961 is shown in the form of a wheel which is rotatably mounted on a trunnion, shown in section, formed on a supporting bracket 961' and secured against displacement by a collar "Z2, a gear llbeing cast integral with or secured on said wheel, said gear n meshing with a drive pinion or gear 8614, which is secured on a trunnion having gearing in the bracket 961. The drive is applied to pinion 6614 by means of gears 9616 and 9611 and a flexible drive coupling similar tothat shown in Fig. 4, the Bear Z6 being secured on the trunnion 89h, and the gear 8611 being mounted on an extension ofzcrossf. head 961'. y

The wheel 961 is formed with an annular cham-` ber 9618, the material being fed to this chamber through hose 9615 which is connected to a bore formed in the bracket 961' and the wheel trun-V nion and communicating with said chamber through a plurality oi' radial holes in said trun- ,i m'on and grooves or a slot Il formed in slid wheel, as shown in the drawings. l

While the wheel 981 'is shown as provided with a driving means, it will be obvious that it could be rotated through friction with the ware or mold. However, by driving the wheel in synchronism with the rotation Yof the attachment and/or mold.4 accurate laying of the pattern. encrustation, design, etc., is ensured. i

The wheel 961 is capable of producing eii'ects too numerous to' mention. the working surfaces of both the wheel and member 88k. Fig. 16. being adapted for applying any desired conngiiration or design, either engraved or in relief and with or' without additional material.

With reference to Fig. 16, the unit Ik is shown as comprising a cylinder 98k', said cylinder having a piston 96k! therein. compression spring 95k3 and guide pin 96M, the cylinder being provided with adjustable heads or bushings, one of which is provided with airexhaust vents which also serve as sockets for a Spanner wrench or analogous tool while the piston stem has a sliding nt in the other, the member 96k being secured on said stem.

In this instance, the material is preferably supy plied through the charger 66, the hose 96e! being attached to the nipple Tiel, (see Fig. 6) and a T' head nipple being secured in the passage nel,

Figi 16, to which ilexible members 'or hose ki and 9615 are secured, the hose 861:6 connecting with a chamber 961c8 formed in the member "1c and communicating with the clay contacting surface of said member through ducts or vents ICH.

The piston 96k2 (see Figs. 6, 8 and 16) is preferably retracted by air or other uid under pressure and advanced by a spring 96162. Air under pressure is conducted to the piston chamber through hose 96M, line lill, groove 1Ic2, line i' 13e', and nipple 13el, the latter being a connection to which a hose leading to a Vcontrol valve' (shown in application Serial No. 13,683) is at tached. 'I'he control valve 'is so constructed that it may be selectively adjusted to cause the operation of the piston at such intervals as .may be desired.

Ordinarily, however, when one or `a plurality Either or both the mold and/or the atachment may be reciprocated and/or rotated. In case intermittent reciprocation and rotation o1' the attachment is desired, the cams 96e and 96f may be found suitable, also cam 96g, Figs. 13 and 14.

The attachments and ware are capable of practically any desired relative reciprocatory, rotative and angular movements by simple and obvious modifications in the contour or the actuating cams and proper-adjustment of parts. Fig. 15 illustrates diagrammaticaliy a 'number of the operating positions of the attachment and mold. Beginning at the left, the attachment is shown working in vertical concentric alignment; next the attachment and mold are shown working in the same horizontal plane but out of vertical alignment; next the attachment is shown working at an angle or tilted and in concentric rotary relation with the mold while the following position shows the attachment at an angle and in eccentric rotary relation with the mold, and the last position shows the attachment and head working at right angles.

Various combinations of the foregoing working positions, too numerous to mention, may be effected, and as the cams and levers may be adjusted while in operation to adjust the phase and extent of movement oi' the parts controlled thereby, these working positions may also be i varied and adjusted while the decorating or other operation ensues.

In regard to supplying the wheel 961 and decorating device 95k with uid, coloring or decorating material, there is provided a charging device, Fig. 9, which comprises a casing 95 which maybe adjustably supported from one of the top frame plates 38o by a bracket 95a, the lower extremity of which is of angle shapeand bored to receive an externally threaded sleeve 95h, the latter being adjustably secured by nuts 95o, the lower extremity of said sleeve terminating in an externally and internally threaded socket head which is' threaded into the casing 95. The casing 95 is provided with an inlet port 95d and outlet port 95e controlled by check valves or analogous means, the port 95d having a pipe or hose connection 95d with a source of supply such as a tank 95.1: or the like, and the port 95e having connected thereto a pipe 95e' formed with a valved T-head, to which a pipe or hose member 95e2 is connected, which leads to the point of application, thel hose 95e2 being herein referredto as the one used for conducting colored decorating material 4to the applicators.

The casing 95 is shown as being formed with additional ports 95j and 95g, the ports 95j having a pipe connection 95f', provided with a check valve assembly 9512, said pipe 95j leading to the supply tank, the object being to expel any decorating iluid that may enter the casing chamber above the piston 95h or which may leak past said plunger, and the port 95g is also provided with a check valve assembly 95g to which a hose or,the like 95g2 may be connected for Withdrawing excess material when the device is used ior appendage work, or the port 95g may remain open and serve simply as an air inlet port. A plug 9593 is shown inserted in the casing 95 below port 95g, to provide for interchangeability oi' the position of said port.

The plunger 95h is secured on the lower extremity of a stem 95h', which has a working ilt in the sleeve 9517, a packing gland 95h2 being threaded in the socket head of said sleeve and the piston 95h also being provided with the usual rings or analogous means to prevent leakage, said stem projecting upwardly through an arm 95a' of bracket 95a, a compression spring 95113 being tremity from a post 951', which is secured to and depends from one of the top plates 38o, and at lts opposite extremity said lever is bifurcated and pivotally secured to a pivot block 95h5 which is adjustably secured on stem 95h by upper and lower collars 95116. Lever 951 is provided with a cam roller 951'2, adapted to contact with a cani 9523, which may be ,adjustably mounted on one of the cross shafts a.

It will be noted that the pressure of piston h on the charge may be regulated by adjusting spring 95h3, which may ensue while in operation. and as the fulcrum point of lever 951 and angu` lar position of cam 9513 may .be varied while in operation, the reciprocation and phase of .reciprocation of said plunger may be likewise varied, to thereby measure the charges of material and time and pressure of application of the same while the device is operating to deliver the charges.

In some instances, it may be desired to vary the stroke ofthe charger plunger 95h independent of the cam 9513, or impart a series of pulsations of varying extent to said plunger, and when such operation is desired, a reduction gear such as Geneva gear 951 may be secured on a. stub shaft 951', which may be mounted in bearings adjacent shaft 80a, and a motion plate 9512 adjustably secured on the shaft 80a and adapted to intermittently actuate the Geneva gear 951. Charge measuring screws 9513 are shown as adjustably mounted in spaced relation around the periphery v of a wheel or disk 9514 whichmay form part of the Geneva gear 951, these screws corresponding number to the slots in the Geneva gear. A further contact member or screw 9515 is adjustably mounted in a side bracket on lever 951', said screw being adapted to contact with the screws 9513 at each intermittent partial revolution of the Geneva gear 951. By adjusting contact screws 9513 relatively to screws 9515, the stroke of the charger plunger 95h may be correspondingly varied independent of the cam 9513, and by adjusting contact screw 9515 independent of screws 9513, the complete cycle of strokes may be varied without varying each individualstroke.

Thus, in the case of the wheel 961 colored decorating uids are supplied to the chamber thereof through the charger 95, hose 95e2, Fig. 9, nipple 13M, Fig. 6, orifice 13f, Fig. 8, passage '|3f'; groove '1312, line 13e3 and hose 9615. The same fluid supplying system is utilized for the decorating attachment of Fig. 16, except that hose 96k5 is employed ybetween the applicator and the pipe 13e3.

It will be noted that the apparatus shown in Figs. 1, 2 and 3 are arranged in substantially the relative position occupied thereby when in assembled relation, except that the attach bracket 8B, Fig. 2, is turned 90 from the position shown to mountthe same on plate 86, Fig. 1. This assembly may be mounted at' P or F, Figs. 10 and 10A, and the number of assemblies depends on the number of lines of production,

which, as illustrated in Fig. 8, is shown to be two, although the machine actually has four lines ofl production, as shown in the parent application, wherein ware of ldiverse character such as plates, bowls. cups and kindred articles as stated therein are made.

The drive for the assembly at station P or F comprises shaft 80a, Figs. 5 and 10, Whichis driven by gears from shaft 89. Shafts 80 and 4l are provid'ed with sprocketgears and connected by a sprocket chain or analogous member 80o and driven in synchronism. Shaft M has a gear l1 driving gear 61a, Fig. 12, on cam shaft 62e which raises and lowers the chuck 62. Shaft 86 may be independently powered by motor 66h and this shaft is connected by gears 61 and 61a, Fig. l2, drivi-ng shaft i which rotates the chuck 62. Shaft lil is driven by chain 80d, Fig. 10, which transmits power from overhead shaft 80', Fig. 19, driven by main drive motor 80e through gears lll' and 800.

It has been stated hereinbefore that the shaft "b may be maintained stationary by tightening screw "j, Fig. 4. The drive shaft lich-81C! is, of course, disconnected when this is done. Obviously, with shaft b held against rotation, then gears I9 and "a, Figs. 7 and 1'6, are locked thereby holding bracket 981 stationary on sleeve 89h and, as will be obvious, the bracket may be locked in any angular position desired with this arrangement.

\To adjust the wheel l to the position illustrated in the right hand diagram, Fig. 15, the flexible drive 3 4, Fig: 2, is disconnected and the xm "i loosened and turned approximately 90 a position paralleling the slot in the bracket lli. .'I'he wheel lil can then be loosened on the arm Iii, swung to a vertical position and tightened. If it is desired not to drive the wheel and to permit it to be rotated by contact with the work asvhereinbefore mentioned, the drivevsimply remains disconnected. It will be obvious from the foregoing how adjustment maybe made to relocate the wheel to correspond with the other positions of adjustment shown in Fig. 15.

Where the bracket i is turned at right angles to shaft "hand locked in this position with the, decorating wheel adjusted to the position shown in the right hand diagram, Fig. 15, it will be obvious that the shaft b and consequently the decoratingA wheelv lll may be shifted radially either in contact or out oi' contact with the ware or lifted and lowered as desired.

Where it is desired to decorate ware in succesison but with different decoration, a bracket i may be mounted from each of the four extensions l of attachment Il, Fig. '1. After one or more pieces have been decorated, the attachment Il is rotated by rack 86d, Fig. 1, to bring the next decorating device into working position.

The reference character M, Fig. 2, rdesignates a ware support bearing ware adapted to be transported by conveyor I to a position over chucks l2 at the decorating stations P or F. Bald chucks raise and lift the support out ofthe open bottom trays of the conveyor toward the decorating instrument L Suction may be applied to the support whilst seated in the chuck to grip the same thereto. The ware su'pports may be hollow as shown to accommodate hollow ware or may have a raised surface for the reception of fiat ware. All is described in greater detailin the parent application.
